To all whom 'it may concern: y

Be it known that I, HABLAN J. MAYNARD, a citizen of the United States, and resident of Greenwich, county of Fairfield, State of Connecticut, have invented certain new and yuseful Improvements in Holders for Feeding or Nursing Bottles, of which the following is a specication.

My invention is a sectional and detachable holder for vessels and particularly for nursing or feeding bottles, in which it is desirable to maintain a liquid at an approxi-A mately uniform temperature, either higher or lower than atmospheric temperature for .a limited period. l

The invention consists in constructingV a holder so that it can be readily heatedf or cooled by means of a suitable liquid, and then applied to the vessel to reinforce the temperature of the latter and tend to preserve' it uniform, as fully set forth hereinafter and illustrated in theaccompanying drawing, in which- Figure 1 is a sectional view of my improved holder applied to a nursing bottle;-

of the holder; and Figs. 3 and 4 are sectional views illustrating modications.

The holder has a body A which consists of an inner casing l, preferably of metal, and a surrounding non-conductor of heat 2, which is preferably within an outer protecting casing 3. The non-conductor may be a layer of felt, paper, pulp, or otherlcovering for the receptacle 1, or it may be/fa body of air inclosed between'ihe receptacle and the external casing 3 of metal or.l other material.

At one end of the body is a cap B. As

, shownin Figs.' 1 and 2, the cap is a metallic shell'4 witha flange 8 having L-shaped slots 9 adaptedto receive pins or,shoulders 7 on the. body to form a bayonet joint connection between the cap and body. Within the shell 4 a lining 5 of felt, paper, or other non-con- .ductor of heat is confined by flanges 12, 13.

The interior of the holder conforms generally to the form of the vessel C to be held, and means are provided to center the vessel in the holder so as to be nearly but not quite in contact therewith. As shown in Fig. l, the vessel is a feeding or nursing 'bottle and a boss or projection 6 at the bottom of the casing 1 extends into the usual bottom recess of thebottle and centers the body of the bottle in the receptacle, while the lining 5 bears on the tapering neck of the bottle and centers the upper portion of the latter. The neck of the vessel must protrude through the holder and the latter has at one end an opening X for this purpose. In Figs. l and 2,

` this opening is in the cap as shown.

Ifit is the purpose to maintain the contents of the Vessel at a given temperature above atmospheric temperature, the vessel C is withdrawn from l,the holder A, the latter is filled with a liquid at a temperature slightly above that to be maintained in the vessel, and the latter is filled with the liquid to be held. The contents of the holder are poured out as soon as the holder is properly heated,

andthe vessel is inserted and secured by the cap. As the contents of the vessel C are withdrawn the entrance of air tends to reduce the temperature of the remaining portion of said contents, b ut such reduction is prevented by the reinforcing heat of the casing 1', which itself is protected from being rapidly cooled by the external air by the surrounding non-conductor 2. In the case of a feeding or nursing bottle, it has been found that the food will be thus preserved at a proper feeding temperature, throughout the most extended time required for the extraction of the contents of the bottle; a result which it may be remarked, experiments show cannot possibly be obtained by merely covering the bottle with a non-conducting acket. I

If the contents of the vessel are to be maintained for time at a temperature lower than atmospheric temperature, the holder is first cooled by being filled with a properly cooled liquid, before inserting the vessel containing the liquid to be kept cool. The cap may be at the bottom of the holder and screw-flanged to screw onto threads at the bottom of the casing as shown in Fig. 3. In this case, the openingX for the neck of the bottle is at the upper end of the casing with a flange 15 for centering the neck of the bottle, and the holder 1s inver-ted and a cork or plug inserted in the opening` X to permit it to retain the heating or cooling liquid until the holder is at the desired temperature. A non-conducting covering may be applied to the casing 1 without anlbiternal casing. Thus in Fig. 4, a cover .ing 2 of papier mch is shown, and the exterior of suoli covering is made Watertight so as not to absorb moisture, by a coating 16 of shellac varnish, enamel, etc.

Itwill be seen that by forming the holder to receive a liquid, the proper temperature may be imparted to it without the use of lamps, elect-ric heaters, etc. which invariably overheat and are otherwise objectionable.

While I have referred to the holder as adapted for use with a feeding or nursing bottle, it is evident that it may be applied to and employed in connect-ion with similar vessels. In some cases the casing 1 may be of china'or -earthenware and heated oil or solutionsy may be employed for heating or cooling it. which heat is added or from which heat is extracted, for maintaining the temperature of the inclosed vessel, is preferably, of sheet metal, of suitable thickness for storing the desired amount of heat. The air space between the bottle andthe holder is important, as it prevents theI heat from the lining from being imparted suddenly to the vessel, causing'the contents of the vessel to take up the heat about in proportion as they lose heat through the entrance of air to replace the contents of the vessel. The air space also prevents the escape of heat from the vessel through the wall of the holder,

Without limiting myself to the construction shown, I claim l. In a nursing or feeding device, the combination with a bottle, of a temperature maintaining /holder therefor, said holder comprising two parts which are interlocked and separable to permit of removal and in sertion of the bottle, one of said parts having The lining of the holder, to`

v W itncsses an opening through which the neck of the bottle protrudes and being constructed to bear on the neck ofthe bottle and center thc bottle in the holder, and the other part having a bearing upon the bottom of the bottle to sustain the bottle in the holder, one of said parts having an .inner met-al casing larger than the bottle, whereby an air space surrounding the bottle is provided, and a nonconducting covering upon said casing, and the bottle having a neck adapted to projcct substantially above the upper end of the holder, for the purpose set forth.

2. The combination with a nursing or feeding bottle, of fa holder surrounding the bottle and having an opening in its upper end through which 'the neck ofthe bottle prot-rudes, said holder comprising a body A and a cap portion B; the body As com risinv an inner metal Casin larver-- than the bottle whereby an air space is produced between the casing and bottle, an outer metal casing, and intermediate nonconducting material; said cap portion comprising a metal shell or casingand an inner layer of non-conducting material adapted to bear upon the neck of the bottle; the said comprising the holder being provided with interlocking means and cap and bodv adapted to center and clamp the bottle be-y I bottomgof the body,

tween the cap and the for the purpose set forthn In testimony whereof l affix my signature in presence of two witnesses.
